Sahih al-Bukhari 67:10
Narrated Anas bin Malik:
`Abdur-Rahman bin `Auf came (from Mecca to Medina) and the Prophet (ﷺ) made a bond of brotherhood between him and Sa`d bin Ar-Rabi` Al-Ansari. Al-Ansari had two wives, so he suggested that `Abdur- Rahman take half, his wives and property. `Abdur-Rahman replied, "May Allah bless you with your wives and property. Kindly show me the market." So `Abdur-Rahman went to the market and gained (in bargains) some dried yoghurt and some butter. After a few days the Prophet (ﷺ) saw `Abdur-Rahman with some yellow stains on his clothes and asked him, "What is that, O `Abdur-Rahman?" He replied, "I had married an Ansari woman." The Prophet (ﷺ) asked, "How much Mahr did you give her?" He replied, "The weight of one (date) stone of gold." The Prophet (ﷺ) said, "Offer a banquet, even with one sheep."

حَدَّثَنَا مُحَمَّدُ بْنُ كَثِيرٍ، عَنْ سُفْيَانَ، عَنْ حُمَيْدٍ الطَّوِيلِ، قَالَ سَمِعْتُ أَنَسَ بْنَ مَالِكٍ، قَالَ قَدِمَ عَبْدُ الرَّحْمَنِ بْنُ عَوْفٍ فَآخَى النَّبِيُّ صلى الله عليه وسلم بَيْنَهُ وَبَيْنَ سَعْدِ بْنِ الرَّبِيعِ الأَنْصَارِيِّ وَعِنْدَ الأَنْصَارِيِّ امْرَأَتَانِ، فَعَرَضَ عَلَيْهِ أَنْ يُنَاصِفَهُ أَهْلَهُ وَمَالَهُ فَقَالَ بَارَكَ اللَّهُ لَكَ فِي أَهْلِكَ وَمَالِكَ دُلُّونِي عَلَى السُّوقِ، فَأَتَى السُّوقَ فَرَبِحَ شَيْئًا مِنْ أَقِطٍ وَشَيْئًا مِنْ سَمْنٍ فَرَآهُ النَّبِيُّ صلى الله عليه وسلم بَعْدَ أَيَّامٍ وَعَلَيْهِ وَضَرٌ مِنْ صُفْرَةٍ فَقَالَ " مَهْيَمْ يَا عَبْدَ الرَّحْمَنِ ". فَقَالَ تَزَوَّجْتُ أَنْصَارِيَّةً. قَالَ " فَمَا سُقْتَ ". قَالَ وَزْنَ نَوَاةٍ مِنْ ذَهَبٍ. قَالَ " أَوْلِمْ وَلَوْ بِشَاةٍ ".
